 135 <p>The <a class="link" href="vector.html" title="Class template vector">vector&lt;T&gt;</a> class stores a dynamic array of values. Internally, the data is stored in an OpenCL buffer object.</p>
 136 <p>The vector class is the prefered container for storing and accessing data on a compute device. In most cases it should be used instead of directly dealing with buffer objects. If the undelying buffer is needed, it can be accessed with the get_buffer() method.</p>
 137 <p>The internal storage is allocated in a specific OpenCL context which is passed as an argument to the constructor when the vector is created.</p>
 138 <p>For example, to create a vector on the device containing space for ten <code class="computeroutput">int</code> values: </p>
